Description
Standard PC has a ceiling when it comes to heat. When a part must live in hot environments for long stretches, or pass reflow soldering, you need a resin with deliberately improved thermal stability. High Temperature Resistant Virgin PC Resin is made for exactly that: copolymers or special formulations push the heat deflection temperature higher while keeping PC's transparency, impact strength, and electrical insulation. Common uses include automotive lighting, appliance heating parts, LED holders, connectors, and coil bobbins.
Its key figures are heat deflection temperature (HDT) and glass transition temperature. Standard PC sits around 125–130°C on HDT; high-temperature grades reach 135–150°C, and copolymer versions go higher still, with a correspondingly higher glass transition so parts resist softening under prolonged heat. The trade-off: melt flow runs a little lower and processing temperature rises, so molding and tooling demand more.
Available grades cover SABIC's Lexan and Covestro's Makrolon heat-resistant lines, plus domestic high-heat PC from Wanhua, Daphoon, and Lihuayi. We supply specified brand and batch, and can add UV stability or other additive options for the application.
Processing High Temperature Resistant Virgin PC Resin starts with drying-around 120°C for four hours or more. Because the melt runs hot, raise both barrel and mold temperature so the cavity fills completely. Keep dwell time at high temperature short to avoid degradation and yellowing, and remember it is sensitive to solvents, oils, and alkaline cleaners, so keep loaded parts away from these to prevent environmental stress cracking.
